In Xcode, pressing ⌘B (build target) can build the project, it will generate the build in the path ~/Library/Developer/Xcode/DerivedData/{AppName}-{hash}.

  • How could I know the whole path of the build (with the hash value) by a script? Can I find that path in my .xcodeproj?
  • When I use ⇧⌘U (build test target only), where can I find the test target build?

The build paths can be controlled using BUILT_PRODUCTS_DIR , PROJECT_TEMP_DIR , CONFIGURATION_BUILD_DIR and CONFIGURATION_TEMP_DIR etc . https://help.apple.com/xcode/mac/11.4/#/itcaec37c2a6

There's no need to extract them from some non-public file format specification.

If you must do it, init a temporary git repo with a xcodeproj file in it. Commit it. Make a change in one of the variables and then run git diff.

  1. How could I know the whole path of the build (with the hash value) by a script?
  1. Change to the same folder where your project or workspace is
  2. Run xcodebuild -showBuildSettings
  3. May need to add the proper scheme or target. See man xcodebuild

See sample below to find by script

  1. When I ... build for test target only, where can I find the test target build?

It will be in the same folder with a name similar to <Test_Target_Name>-Runner.app. This is useful as you can use for Cloud device testing services.

# This example works with Xcode project with a single scheme
# Echo to stdout
xcodebuild -showBuildSettings
xcodebuild -showBuildSettings | grep CONFIGURATION_BUILD_DIR

# save to a variable for use in your script
#   A little brutal, so I'm open to other ways to do this.
CONFIGURATION_BUILD_DIR=$(xcodebuild -showBuildSettings 2> /dev/null | grep CONFIGURATION_BUILD_DIR | sed 's/[ ]*CONFIGURATION_BUILD_DIR = //')
echo $CONFIGURATION_BUILD_DIR

If you are using Xcode Server Bots

cd ${XCS_PRIMARY_REPO_DIR}
xcodebuild -showBuildSettings

Sample output:

/Users/roblabs/Library/Developer/Xcode/DerivedData/openmaptiles-ios-demo-eectbiabcmhajpdbcoqnaipiaqpd/Build/Products/Release-iphoneos

As noted in https://stackoverflow.com/a/57512068,

The default value is $(BUILD_DIR)/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)

For further documentation on the build setting properties, see Build Setting Reference at developer.apple.com. The link that @puio listed is also useful.
